Enable Ring DHCP Snooping
To enable DHCP snooping within the ring, click Advanced and check the
Enable DLR DCHP Snooping checkbox.
Ring DHCP snooping restricts the broadcast of DHCP requests from going
beyond the ring. Only devices in the ring receive address assignments from the
DHCP server.
DHCP snooping is enabled by default. If you are not using DLR DHCP, you
must disable Ring DHCP Snooping to use DHCP server functionality outside
of the ring.
